iOS Question How to kill the previous pages

[ciginfo]

In the code below, two questions.
1°) Why the green and yellow do not appear on the page when I call respectively 'Cherche.RootPanel.Color = Colors.Green' and 'Cherche.RootPanel.Color = Colors.Yellow' with the segmentedcontrol1?
2°) How to kill the precedent page when i use segmentedcontrol1 ? When I used alternately segments segmentedcontrol1 I display the appropriate pages, but when I want to return to Page1 using the top bar left backButton I see through all the previous pages before reaching Page1 ? (See attached file)

'Code module

Sub Process_Globals
    Public NavControl As NavigationController
    Private Page1, Cherche As Page
    Private LblCherche, LblBJ, LblLayoutMain As Label
    Private BtnCherche As Button
    Private segmentedcontrol1 As SegmentedControl

End Sub

Private Sub Application_Start (Nav As NavigationController)
    NavControl = Nav
    Page1.Initialize("Page1")
    Page1.Title = "SittingBreak"
    Page1.RootPanel.Color = Colors.White
    NavControl.ShowPage(Page1)
    Page1.RootPanel.LoadLayout("Main")
End Sub
Sub BtnCherche_Click
    Cherche.Initialize("Cherche")
    Cherche.RootPanel.LoadLayout("Cherche")
    Cherche.Title = "Cherche"
    LblBJ.Text = "Bonjour"
    segmentedcontrol1.BringToFront
    NavControl.ShowPage(Cherche)
End Sub
Sub SegmentedControl1_IndexChanged (Index As Int)
Select Index
    Case 0
        Cherche.Initialize("Cherche")
        Cherche.RootPanel.Color = Colors.Green
        Cherche.RootPanel.LoadLayout("Cherche")
        Cherche.Title = "Cherche"
        LblBJ.Text = "Bonjour"
        segmentedcontrol1.BringToFront
        NavControl.ShowPage(Cherche)
    Case 1
        Cherche.Initialize("Cherche")
        Cherche.RootPanel.Color = Colors.Yellow
        Cherche.RootPanel.LoadLayout("Cherche")
        Cherche.Title = "Cherche"
        LblBJ.Text = "Bonsoir"
        segmentedcontrol1.BringToFront
        NavControl.ShowPage(Cherche)
End Select
End Sub
Private Sub Page1_Resize(Width As Int, Height As Int)
   
End Sub

Private Sub Application_Background
   
End Sub

The problem is that you initialize every time a new Page !
Remove
Cherche.Initialize("Cherche")
Cherche.RootPanel.LoadLayout("Cherche")
from the subroutines and add it in Application_Start.
